The VS2010 SP1 Beta has been released from Microsoft and with it a few bugs got fix, like the bug with the weird copy and paste issue inside VS2010. Read all about it in my previous post here: Problems with copy and paste in VS2010

I have received this email from Microsoft:

VS2010 Copy / Paste functions are not working as expected which you submitted at the Microsoft Connect site.

Hi everyone, I'm writing to let you know that this cut/copy/paste bug is fixed in the Visual Studio 2010 Service Pack 1 Beta, which was just released last week, so we're resolving this bug as Fixed. We would encourage you all to download the SP1 Beta from http://go.microsoft.com/fwlink/?LinkId=207130, which should eliminate the sporadic copy/paste failures you're experiencing. If you still see issues after installing VS 2010 SP1, please file a *new* Connect bug so that we can investigate separately. Thanks again for your feedback […]

Before you install VS2010 SP1 Beta, you may want to read this post from Scott Hanselman about the implications of going Beta.

Cheers
